Expense Reports default "complete"

I haven't been able to locate any info on this in the help resources or the user forum.

When our sales people create a new expense report, the form automatically has the  complete check box checked when they start and long before they finish.  This results in them saving their er and not being able to go back and complete or edit the reports.  The Administrator can edit the report and uncheck this box, so they can complete their reports, but it seems like this should not be checked except by the employee  when they are complete!

Why is this the default setting or is this a defect issue with our account that should be reported?  If it isn't, does anyone know how to permanently turn off that default setting?  Thanks for any help you can offer.
